PBOC Datasheet, PDF (1/2 Pages) OPLINK Communications Inc. – Polarization Maintaining Beam Splitter

Polarization Maintaining Beam
Splitter/Optical Circulator Hybrid
PBOC Series
Product Description
Oplink’s Polarization Maintaining Beam Splitter/Optical Circulator (PBOC) hy-
brid module combines the functionalities of a beam splitter and a circulator
while providing polarization control. It is specially designed for optical mod-
ule or subsystem integration, such as dynamic gain equalizers (DGEs), planar
lightwave circuit (PLC) devices, optical waveguide modules and MEMS based
modules. The PBOC features low insertion loss, low dispersion and compact
packages.
Oplink can provide customized designs to meet specialized feature applica-
tions. Also, Oplink offers modular assemblies that integrate other components
to form a full function module or subsystem.
